Similarities between China, Germany, and the Soviet Union essays

Similarities between China, Germany, and the Soviet Union essays The events that occurred in China under Deng Xiaoping s rule are similar to the events that occurred in Nazi Germany under Hitlers rule and the Soviet Union under Stalins rule to a great extent. Successful dictatorships use many techniques to win their countrys support. Propaganda, indoctrination, controlled participation, direction of popular discontent, and force and terror are all commonly used in this form of government; and all are techniques the leaders of those three countries used time and again. All of the media, such as radio and newspapers, was altered to portray the governments as being successful and honorable. No information that could possibly uncover the governments truths was allowed to be exposed. Furthermore, the leaders of the countries began to include their beliefs and ideas into the nations schools and youth programs alike. Children were exposed to the communist and fascist ideas at young ages to ensure continued government support. Also, these regimes used th e technique of controlled participation. People who are allowed to participate in and contribute to something are more likely to support it. In China they introduced the spy-on-your-neighbour campaign, and local authorities had no problem recruiting thousands of neighbourhood informants and auxiliary police to enforce the crusade. One problem the governments did face was that of those who did not believe or did not support their rulers ideas. The solution: direction of popular discontent and the use of force and terror. If civilians still refused to believe the ideologies of their leaders, the governments would try to put the blame on others. In Nazi Germany, Hitler blamed the Jews, Slavs, political opponents, union leaders, ministers of religion, pacifists, and homosexuals for Germanys economic problems at the time. After the Tiananmen Square incident, the Chinese leader placed the blame on the th...

Television History and the Cathode Ray Tube

Television History and the Cathode Ray Tube The development of electronic television systems was based on the development of the cathode ray tube (CRT). A cathode ray tube aka picture tube was found in all electronic television sets up until the invention of the less bulky LCD screens. Definitions A cathode is a terminal or electrode at which electrons enter a system, such as an electrolytic cell or an electron tube.A cathode ray is a stream of electrons leaving the negative electrode, or cathode, in a discharge tube (an electron tube that contains gas or vapor at low pressure), or emitted by a heated filament in certain electron tubes.A vacuum tube is an electron tube consisting of a sealed glass or metal enclosure from which the air has been withdrawn.A cathode ray tube or CRT is a specialized vacuum tube in which images are produced when an electron beam strikes a phosphorescent surface. Besides television sets, cathode ray tubes are used in computer monitors, automated teller machines, video game machines, video cameras, oscilloscopes and radar displays. The first cathode ray tube scanning device was invented by the German scientist Karl Ferdinand Braun in 1897. Braun introduced a CRT with a fluorescent screen, known as the cathode ray oscilloscope. The screen would emit a visible light when struck by a beam of electrons. In 1907, the Russian scientist Boris Rosing (who worked with Vladimir Zworykin) used a CRT in the receiver of a television system that at the camera end made use of mirror-drum scanning. Rosing transmitted crude geometrical patterns onto the television screen and was the first inventor to do so using a CRT. Modern phosphor screens using multiple beams of electrons have allowed CRTs to display millions of colors. A cathode ray tube is a vacuum tube that produces images when its phosphorescent surface is struck by electron beams. 1855 German,  Heinrich Geissler  invents the Geissler tube, created using his mercury pump this was the first good evacuated (of air) vacuum tube later modified by Sir William Crookes. 1859 German mathematician and physicist,  Julius Plucker  experiments with invisible cathode rays.  Cathode rays  were first identified by Julius Plucker. 1878 Englishmen,  Sir William Crookes  was the first person to confirm the existence of cathode rays by displaying them, with his invention of the Crookes tube, a crude prototype for all  future  cathode ray tubes. 1897 German, Karl Ferdinand Braun invents the CRT oscilloscope - the Braun Tube was the forerunner of todays television and radar tubes. 1929 Vladimir Kosma Zworykin  invented a cathode ray tube called the kinescope - for use with a primitive television system. 1931 Allen B. Du Mont made the first commercially practical and durable CRT for television.
